In the present instance, the opposite top and bottom ends of the rear wall'are' each formed with parallel longitudinal slots 16 and lying in contact with the rear face of the back wall behind the slots 16 are arms 17 carrying set screws 18 working within the slots 16 and adapted to grip the opposite walls of the slots to hold the arms 17 against movement. The arms at the top of the rear Wall project upwardly from such wall, while those at the lower end thereof extend downwardly therefrom and suitably fastened to or formed in- .tegral vwith the outer ends of each pair of arms is an appropriate form of clamp 19 designed to surround and grip the adjacent pipe coupling or fitting, as clearly illnstrated in Fig. 1 of the drawings, whereby the-protector will be securely held in place. From the foregoing description taken in connection with the accompanying drawings, the construction, mode of operation and manner of employing my invention will be readily apparent. It will be seen that I have provided a protector or guard for the water glasses of steam boilers whereby fly ing glass, in the event of the Water glass breaking, will be prevented and the accidents incident thereto eliminated.

While I have herein shown and described one preferred form of my invention by Way of illustration, I wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made withinthe scope of the claim Without departing from the spirit of the invention.

I claim:

A guard of the class described coniprising a back wall, parallel plates bent to form front and side walls detachably connected with the back wall and forming pockets, the front and rear Walls of said pockets being formed with slots, and transparent plates Within said pockets and removable therefrom.

In testimony whereof I afiix my signature in presence of two witnesses.
